BALL-BEARI NG.

SPECIFICATION forming part of Letters Patent No. 434,479, dated August 19, 1890. Application iled January l1, 1890. Serial No, 336,701. (No model.)

To all whom it may concern:

Be it known that I, GEORGE FREDERICK SIMONDS, engineer, a citizen of the United States, and a residentof Fitchburg, Massachusetts, have invented certain new and useful Improvements in Ball-Bearings, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to axle and other bearings in which spherical rollers or balls are employed to diminish the friction.

An important feature of my said invention is the construction of the bearing with the balls arranged in circular series or groups of different diameter and in different planes between concentric and plane surfaces formed on inner and outer rings or annular or tubular pieces. I arrange the balls of the series of larger diameter to bear against and roll upon plane bearing-surfaces and the balls of the series of smaller diameter to bear against and roll upon concentric bearing-surfaces on the said rings or annular or tubular pieces, or vice versa. piece or sleeve having suitable concentric and plane surfaces with two correspondinglyshaped rings or annular pieces. In some instances I provide the said tubular piece or sleeve with an external rib or collar, on which are formed the plane and one of the concentric surfaces, and arrange it within rings or annular pieces having corresponding internal ribs or flanges. In other instances I make the said tubular piece with an internal circumferential projection or rib, on which are formed the plane and one of the concentric surfaces, and I arrange two rings or annular pieces having corresponding external ribs or flanges within the said tubular piece. My improved bearing can, however, be provided with any other suitable number of rings or annular or tubular pieces.

In the accompanying drawings I have shown how my said invention may be conveniently and advantageously carried into practice.

Figure l is a longitudinal central section of a bearing constructed according to my present invention for a car-axle or the like. Fig. 2 is a vertical central section of a bearing constructed according to my said invention for I prefer to combine a tubular surface a concentric with 'the shaft or axleY and which is provided with a circumferential l projection, rib, or collar having a surface a2 concentric with the said shaft or axle, and two plane surfaces a3 a4 parallel to each other and perpendicular to the said concentric surfaces.

b b are two rings or annular pieces, each having surfaces b b2 concentric with the said surfaces a a2, and plane surfaces b3 b4 parallel to the said plane surfaces a3 a4. These concentric and plane surfaces form, circular channels or cavities of different diameters, in which are'arranged in circular series ,or groups the balls c c. The balls c bear against and roll upon the concentric surfaces a b and serve to support the shaft or axle, or the part in which the said shaft or axle rotates', or which rotates thereon. The balls c are arranged between the concentric and plane surfaces a2 a4 on the said tubular piece a, and the concentric and. plane surfaces b2 b4 on each ring b, and these balls bear against and roll upon the said plane surfaces a4 b4 and serve to resist thrust or endwise motion of the parts vrelatively to each other.

In the bearing shown in Fig. l the tubular piece or sleeve a is secured upon the axle A y by means of screws Land the rings or annular pieces b are fit-ted in a box or casing B,

closed at its ends by covers B B2. Screws e are passed through tapped holes in the cover B2 for the purpose of adjusting the rings b at one end of the box or casing relatively to the rib 'or collar of the tubular piece a, the screws c first moving inward and adjusting the adjacent ring until the balls of thecorresponding series or group are brought to a bearing, and then drawing the box orcasing B toward them until the balls of the series or group at the other end of the said box or cas ing are brought to a bearing. There are four circular series or groups of balls c arranged between the concentric and plane surfaces a a3 on the said tubular piece or sleeve a and the concentric and plane surfaces b b3 on each ring b. Suitable rings f are arranged IOO between these series or groups of balls to separate the balls of one series from those of another series.

In the bearing shown in Fig. 2 the tubular piece a is secured by means of screws (Z in the nave or hub C of a pulley or similar rotating piece of machinery.

The rings b are fixed upon the shaft A as follows-viz: a transverse slot or groove A is formed in the shaft A, and in this slot or groove is fitted a metal bar or key g, preferably of triangular form in transverse section. This key project-s above the shaft and engages in recesses or notches o in the rings b, so that by turning the adjusting-screws c, which are passed through one ring b and screwed into the other ring b, the said rings may be drawn together upon the key, and will thus be securely held in place upon the shaft.

It is obvious that various kinds of bearings can be constructed with balls arranged in circular series or groups, which are of different diameters and are situated in different planes, as hereinbefore described.

Certain features of construction ,shown and described, but not claimed in this application, are shown, described, and claimed in applications filed by me, Serial Nos. 331,039, 336,403, and 336,700.

Vhat I claim isl. A ball-bearing wherein the balls are arranged in circular series or groups of different diameters and in different planes between concentric and plane surfaces formed on inner and outer rings or annular or tubular pieces, for the purposes above specified.

2. In aball-bearing, the combination of inner and outer rings or annular or tubular pieces having concentric and plane surfaces which, when the said rings or annular or tubular pieces are placed in their proper relative positions, form annular channels or cavities of different diameters and in differentplanes, and balls arranged in circular series or groups in the said channels or cavities, substantially as and for the purposes above specified.

3. In a ball-bearing, the combination of a ring or annular or tubular piece a, having concentric surfaces a a2 and plane surfaces ai a4, rings or annular pieces b, having concentric surfaces b b2 and plane surfaces b3 b4, and balls c c', arranged in annular channels or cavities of different diameters formed by the said concentric and plane surfaces, sub` stantially as and for the purposes set forth.

4. In a ball-bearing, the combination of a ring er annular or tubular piece a, having concentric surfaces a c2 and plane surfaces as a4, a ring or annular piece b, having concentric surfaces b b2 and plane surfaces b3 b4,

and balls c c', arranged in annular channels or cavities of different diameters formed by the said concentric and plane surfaces, one

of the saidrings or annular pieces being adjustable relatively to the other, substantially as and for the purposes set forth.
